In this paper, two assemblies of special test equipments have been designed and fabricated by authors in our laboratory: namely Catalyst Molding Process Analyzer and Catalyst Mechanical Process Tester. These new skills are developed for the dynamic studies on whole mold forming process and crushing process of Fe-Cr WGHS catalyst pellet. Based on the orthogonal experimental design, the effects of some factors during the forming process of solid catalyst, such as predensification proportion, calcination time, calcination temperature and content of graphite on the mechanical strength of catalyst pellets are systematically examined, and the molding conditions have been optimized. Based on the experimental data, the relationship between catalyst density and forming pressure are educed, and the physical significances of some related parameters are described. The parameter of macro scopic elastic moduls has been suggested to character the mechanical properties of molding catalyst. The effects of molding pressure on mechanical properties of catalyst pellets are discussed, and results show that there exists a optimal molding pressure for the ideal mechanical properties: when over-high or over-low pressure is applied, the specific surface area and side crushing strength of catalyst pellets will decreased. The "rebound effect" will be undermined by the unsuitable pressure maintain process, resulting in the apparent decrease of mechanical strength of catalyst pellets.

By regression of experimental data, therules of the linkage between these factors, which will provide a theoretical basis for designing BBP with different scales.3 Using thermal analysis technology and dynamic thermogravimetry, the paper studies combustion kinetic characteristics of 3 types of agricultural crops at different rate of temperature rise, and thus, achieved dynamic parameters of these fuels at different rate of temperature, established dynamic model of straw combustion, which reflects the dynamic process in the fast combustion area.4 Characteristics of straw briquette combustion was experimented, focusing on the impact of straw type, temperature, air supply, and density, diameter, and weight of briquette on the combustion speed, and the following conclusions were drawn:(1) combustion of straw briquette fuel is static permeation diffusion combustion;(2) temperature has a larger impact on the speed of straw briquette combustion than air supply; the higher the combustion temperature is, the faster volatilizable component separates out, and the less steady the combustion is;(3) density of briquette fuel has impact on the speed of volatilizable component separation and therefore the combustion speed;(4) increase of diameter and weight of briquette fuel increases the average combustion speed in the initial stage, and that in the later stages is comparatively steady;(5) the proportion of volatilizable component in straw briquette fuel is high, therefore, the temperature control during combustion under the rational ventilation condition is essential to ensure its safe combustion.5 Using the above-mentioned results of experiments and theoretical analysis, and based on thought of hydraulic driven and bi-direction compression, the hydraulic system and compression parts of the HBP BBP are re-designed in terms of industrialization.

The objectives of this paper were to investigate the simulation and design of continuous multiple-station rolling forming process for a U-Section Steel Bar by CAE software-DEFORMTM Due to the limitation of elements number using a short strip 120mm went through all the stations to simulate the real continuous rolling forming on factory The roller gap was fixed as 0 30mm roll speed was 20 rad/sec and progressive angles were all equal for each rolling process which were the formed angle divided by by the number of station Three rolling processes were selected with 6 9 and 12 stations respectively During simulation processes two cases occurred Case A the strip was through a single station Case B the strip across two stations Because the strip laterals side was stretched and twisted during the process The model of case B closer to the practical process than case A and the calculated stress and strain on the tip of U section for case A were lower than these for case B by up to 15% From the result of case B for each process the stress for 12-station process was smallest 9-station process second and 6-station process next Because less-station can save larger cost and forming time but the bigger stress and strain for 6-station caused wrinkles on lateral sides not found on 9-station and 12-station Therefore 9-station process was a more suitable design than 12-station process smaller stretched and twisted and stress The progressive angles for 12-station was 7 5?

The forming experiment on hemisphere testified that the transforming pattern of MBWK fabrics was similar to woven fabrics under the condition of ignored yarns slippages. In the forming experiment on rectangular box, the obvious yarns slippages were observed during the forming process, so the pin-jointed net model used by woven fabrics didn't adapt to MBWK fabrics. Based on this finding, a new mathematical model using a macroscopic approach was established for predicting the unfolding shape of flat MBWK fabrics after deformation. In addition, the effect of position of constraint yarns on forming results was analyzed.
